There is no physical violence in the entire film, but there are sequences of great terror and suspense.

The film contains some use of the expletive "f*ck" in the English subtitles.

Filmed in the style of reality TV, the participants are equipped with action cameras that capture footages from their perspectives, adding a sense of realism to the film. As the film progresses, there is a build-up of tension as the supernatural occurrences intensify in frequency and the characters interact directly with the entities.

Coupled with numerous jump-scare scenes where doors slam suddenly, or objects fall to the ground, the sense of lingering and sustained threat is intensified.

In one sequence, a character's eyes suddenly turn black and this scares another character.
